Tinyhawk 2 low rssi issue

First I’d like to say hi and hope every one is well in these troubled times! My problem is with a tinyhawk 2 rtf kit I recently purchased, all was well untill it suddenly dropped from the sky with a low rssi osd warning. I made sure all the batteries were ok, rebound it to the controller, reset the controller yet the problem is still there. If anyone has any ideas I would be very grateful. Thanks.
